Last week I had the pleasure to attend the San Diego Bird Festival (California) for the first time. I went to represent Birds & Nature Tours, since I work has one of the main guides for the company. 

The festival kept me busy, between talks and staying at the company booth. But I had also the opportunity to co-lead a field trip with my friend Stan Walens, and also doing some birding in my free time. I would like to thank Richard and Stan for their time on taking me out to see some California specialties and Jackie and Craig for their kindness. It was a pleasure to review friends from trips I lead in Portugal and Spain.

​Below is the list of species that I observed during my stay in California. This was my first time on the West coast, which resulted in 35 new species and a total of 115 species seen.

Today, early in the morning, I was walking back with my moth trap, along the valley near my house (Bombarral, West Portugal), when I heard a rare, but familiar call. It came from the top of a huge blooming eucalyptus, without my binocular, I could only see several small birds fluttering on the treetop. And again it called, it was a Yellow-browed Warbler! Caught off guard, I went back home to get my camera, bins and directional microphone.

This was only my 3rd (self-found) Yellow-browed Warbler, the previous one was during this autumn. Soon as I arrived back, I could see a lot of Chiffchaffs feeding among the eucalyptus flowers, also, a Coal and several Long-tailed Tits. I spotted the bird feeding in the treetop and I set the mic on right away waiting to record some calls. A funny thing I noticed, was the more prolongated feeding action on the same area of the tree, unlike Chiffchaffs.

I was able to record some calls and some (bad) photographs. The moth trapping was not so exciting that night, with just a few Cerastis faceta, but this Siberian surprise was very exciting, just outside my house and a winter record.

Since 2009 I´ve been very enthusiastic on moths, beside birding this became my main hobby. In 2014, I´ve stared sampling on the limestone hills near my house in western Portugal. I keep a database with all individuals recorded and photographs of every new species or variation. Below you will find some photos of the last days:

​On the morning of 29 December 2019, I went to salgados lagoon (Algarve, south Portugal) and found a second-winter ring-billed gull. I took the oportunity to study this plumage, and take some record shots, because it´s the one I´ve seen less.                   

The records of Ring-billed gulls (Larus delawarensis) have been decresing during recent years, in Europe in general and in mainland Portugal in particular. There was a recent article on Birdwatch magazine by Josh Jones ("Rise and fall", Birdwatch November 2019, Issue 329), that analysied the declining records in Europe of this iconic Nearctic gull. 

I remember, back on the early 2000´s, to go to my local patch in S. Martinho do Porto bay and see eight or nine on the beach. Now, I struggle to observe one a year. I went to ebird to check my last sighting in Portugal of this species and was in 29 January 2019, a first winter in Salgados lagoon, so most likely this is the same bird i saw eleven months ago exactly on the same place.

By late December the south coast of Portugal is swarming with Chiffchaffs (Phylloscopus collybita). Sunny days around a reedbed can be very productive if you are interested in get familiar with plumage variation of these busy birds.
Some birds, with good light and the help of a camera, can be aged by the level of wear on wing feathers, and the presence of different generations. First winter birds will show more abraded flight feathers and usually diferent generations in coverts, being the result of a partial post-juvenile moult.
In the case of the bird in the picture, it´s possible to see that some tertials and the central pair of tail feathers was replaced on the post-juvenile moult. Although, from late December onwards we need to keep in mind that adults and first years usualy do a partial pre-breeding moult, and it could simulate first winter plumage, but this new feathers would be fresh!

This afternoon I went to Lagoa dos Salgados (Silves, Algarve) to log 69 species, including this female Ring-necked duck, two first winter Common gull and, at list, 5 Barn swallows. Interesting enough was the fact of some of this birds were activily moulting mid wing, indicating the possibility of wintering in the area.

At the beggining of the afternoon of the 21st December the wind was moderately blowing from SW, as a result of a low barometric pressure that was moving towards the Bay of Biscay. When the low pressure hit the Finisterra area, there was a good weather corridor formed between the Portuguese coast and a cold-front. Looking at the weather chart, sitting at my computer, this looked promissing for some seabird movement, forced to move south by the low pressure. Before driving to Peniche, I texted Pedro Ramalho, and we arranged to meet at the usual spot, and share one car.

When we arrived to Cape Carvoeiro (Peniche), we noticed right away some regular Gannet movement, and soon after, the first flock of Black-legged kittiwakes.

After this distraction we continued our task of tally Kittiwakes, and after one hour we finished with a total of 333! Other highlights included a flock of 6 Northern pintail, and, sadly, very few alcids and scoters.

This was a brief movement, but it´s quite rewarding when one sits at a computer and dares to predict seabird movements, just to find out that it works! But, I must say, most of the time it doesn´t!

I´m not a bird photographer. Having said that, I do take some photos of birds.

I carry binoculars and, the majority of the time, a spotting scope, so, adding a big lens and a DSLR it would be a pain on the neck, literally. When bridge cameras became available I did find those to be perfect for my needs, the portability and the big zoom made this cameras perfect for record shots. 

​I own a Canon SX50 HS and, if you scroll down my blog, you will find the range of photographs it produced, some with very acceptable results. Recently, I decided to test the video option in very challenging conditions, filming seabirds from land at Cape Carvoeiro. I did film a Great skua moving south, at 50x and 60x. The video was made hand held, so I belieave a tripod with a fluid head could make it even better. I was quite amazed by the capability of this small camera in a overcast day.
